Abstract: A method may apply a lubricant material into a tube of a tubing and includes mold device having an annular port for extruding a material to form a tube. The mold device includes a passage for supplying a lubricant material into the tube, and includes an aperture for supplying an air to apply the lubricant material onto the inner peripheral surface of the tube. A flexible coil and a cover sleeve are then applied onto the tube for forming the tubing. The wire may then be easily engaged into the tube of the tubing by the lubricant material.
